CRAMPS/

Can anyone tell me WHAT IS A GOOD REMIDY FOR CRAMPS

Magnesium triple complex - magnesium oxide, magnesium citrate, magnesium asparte - 400mg - 800mg (2x 400mg) for legs/arms will do it in 1/2 hr.

Mixed with water and applied topically or ingested? 

Commonly supplied in 400mg capsules . Toss 1 or 2 in your mouth and chase it with water.  Muscle spasms will vanish in minutes and not return in 24 hrs.
After the first 2, one a day is usually enough.  Muscle spasms indicate magnesium deficiency.   :>(

Health-Science-Spirit - Magnesium Chloride  is a good read about Magnesium. 
When I have a bath I put in 3/4 of a cup of Magnesium Chloride into the hot water. Easily absorbed into the body through the skin this way.
Also Magnesium Oil rather than buy it, make it.  1/2 Mag Cloride and 1/2 Distilled water or good water = mag oil 
Health-Science-Spirit - Magnesium Chloride  is where I buy from. This site will give you an idea of the cost etc.

Ahhh I see I used the same link twice. Second link should be  Magnesium & Supplements – Blants  to give you an idea.
